Solid performance
Does what it says on the tin. Shipping was a bit slow but the product is good.
5 FAQ
Q: Is this compatible with 3.3V logic levels?
A: Yes, the module supports operating voltages from 2.7V to 5.5V.
Q: Does this sensor require calibration?
A: No, the LM75 is factory calibrated and does not need user calibration.
Q: What is the interrupt pin used for?
A: It signals when the temperature exceeds programmed upper or lower limits.
Q: Do you provide an Arduino library for this?
A: It works with the standard Wire library, no specific library required.
Q: What is the maximum cable length for I2C?
A: Depends on bus capacitance, but generally keep wires short for reliability.
